FIGURE 1. The Dockum Group exposures (highlighted in grey) in western Texas and eastern New Mexico (modified after Lehman, 1994a). Fossil localities are spotted (yellow-filled circles) within the corresponding counties of Garza, Howard and Randall (marked in red).

FIGURE 2. Generalized columnar sections of the Dockum Group in Texas in Randall, Garza and Howard counties, including the stratigraphic positions of the cited quarries in bold (modified after Ash, 1976; Lucas and Anderson, 1993b; Martz, 2008; Martz et al., 2013; and Bill Mueller, personal commun., 2014, 2015). Unit numbers and lithostratigraphic correlatives for the Garza County section are taken from Martz et al. (2013).
